JPC or interface converter does not function( while waiting for an answer).

  • Check if PMC ROM cassette, PMC RAM board or interface comverter is mounted on master PCB: or replace the above PCB.
  • Bad ladder or blank PMC cassette. Clear PMC RAM to correct.
LWaiting for PMC ready

  • Replace PMC ROM, PMC ROM cassette, or PMC Ram board.
  • Check the PMC program ( bug in program). Loose contact at I/O module (pos.etc) connector to back panel
b
RAM check error. Transfer error through optical fiber cable.
  • Replace the master PCB or ROM/RAM board additional memory.
  • Wrong combination of ROM chips in system. Check Option Data Sheet against S/W ROM set.
  • Check alarm LED of the units connected by optical fiber cable.
  • Replace master PCB, MDI PCB, connection unit PCB, I/O unit, or optical fiber cable (replace PCB with alarm LED lit. )
c
( high failure rate )
  • Replace PMC RAM if using PC debug. (PMC RAM board).
  • Loose connection of custom LSI’s on PCB’s.
  • Wrong program in PMC RAM board. Clear RAM to correct.

  • Problem with contact of connector of Master PCB to I/O unit.
  • Problem with ACP board.
  • Failure of System s/w EPROM’s.
  • Failure of CRT/MDI power supply – check +5 on CA3, pins 4,5,6 or CP23, pins 1,2; +24 on CD1, pin 14 or CP23, pins 5,6
 d
Get when NMI occurs continually. Either RAM Parity or the power off signal occurs
  • Check cable J91 between the Input Unit and Power Supply Unit, or for a failed Input Unit.
  • Replace master PCB, connection unit, I/O cards D1~D3, or optical fiber cable.
  • Optical Interface ( I/O ~ Master PCB ).
  • IF01A PCB plugged into wrong slot in I/O rack.
